Why Teeth Become Yellow

Most people want a bright, white smile. Unfortunately, teeth tend to become yellow or stained over time, and smiles can become dull and dingy-looking. Yellow teeth can have a number of causes, including lifestyle habits and diet.

•    Naturally Yellow Teeth
Your teeth are made of several layers. Pearly enamel covers the outside of the teeth while a yellow or brown dentin makes up the next layer. Enamel that is excessively worn, poorly mineralized or otherwise flawed can allow the dentin to show through, and teeth will appear yellow.

•    Poor Dental Hygiene
If you are brushing your teeth less than twice a day, you may be more prone to discolored teeth. Plaque is a colorless film that builds up on teeth every day. When it is removed infrequently, it hardens into tartar, which can be yellow or even brown in color. Brushing twice a day and flossing every day can keep this type of discoloration to a minimum.

•    Diet
Soft drinks, coffee, tea, berries and wine all contribute to yellow teeth. These foods and beverages have chromogenic properties, which means that they stain and discolor porous materials including teeth.

•    Tobacco
Smoking and chewing tobacco deposit nicotine on teeth. These stains can be yellow or brown in color and are virtually impossible to remove through brushing alone.
